The middle frame 1112 is used as a connecting and bearing component, and the front frame 1111 and the rear frame 1113 are respectively connected with the middle frame 1112. And the front rack 1111, the middle rack 1112 and the rear rack 1113 surround to form an accommodating space 111a. Body 112 covers frame 111, and body 112 is provided with cabin 1121. Cabin 1121 serves as a cockpit and/or passenger compartment for use by a driver or passenger. The cabin 1121 may be partially embedded in the accommodating space 111a and mounted on the frame 111, so that the cabin 1121 may obtain a larger usage space under the condition that the height of the all-terrain vehicle 100 meets the standard.
As shown in fig. 5-7, middle frame 1112 acts as the structure for all terrain vehicle 100 to carry the core load. The middle frame 1112 includes a first type of beam 1112a and a second type of beam 1112b. The first type of beam 1112a and the second type of beam 1112b are interconnected to form a substantially load-bearing structure. In one embodiment, the first type of beams 1112a are provided in a plurality, and the plurality of first type of beams 1112a are spaced apart and substantially coplanar. Here, a plane on which the first-type beam 1112a is located is set as a plane S. The number of the second type beams 1112b is also plural, and the plural second type beams 1112b are arranged between the plural first type beams 1112a at intervals. It is understood that the first type of beams 1112a can be provided in a number of two, three, or four. Similarly, the number of second type beams 1112b

The first longitudinal beam 1112e includes a first rod 1112f and a second rod 1112g. One end of the first rod 1112f is connected to the first cross beam 1112c, the other end of the first rod 1112f extends toward the second cross beam 1112d, and an included angle between the first rod 1112f and the plane S is A1, and A1 is set to be greater than or equal to 5 ° and less than or equal to 15 °. One end of the second rod 1112g is connected to the second beam 1112d, and the other end of the second rod 1112g extends toward the first beam 1112c and is connected to the first rod 1112 f. The angle between the second rod 1112g and the plane S is A2, and A2 is set to be greater than or equal to 5 ° and less than or equal to 15 °. In this manner, the bottom of middle frame 1112 can be raised upward (away from the running surface) in the front-to-rear direction of atv 100. That is, the bottom of the middle frame 1112 is upwardly convex. Therefore, the ground clearance of the all-terrain vehicle 100 at the middle frame 1112 is improved, and the trafficability of the all-terrain vehicle 100 during driving is effectively increased.
In one embodiment, the angle A1 between the first rod 1112f and the plane S is greater than the angle A2 between the second rod and the plane S. In this manner, a better ride quality is maintained as ATV 100 traverses a continuously uneven surface. Further, the first-type beam 1112a and the second-type beam 1112b are each cut from a steel pipe. So the material taking and the processing are both convenient. The first rod 1112f is welded to the first beam 1112c and the second rod 1112g is welded to the second beam 1112d. The first and second rods 1112f and 1112g are connected by welding. The first bars 1112f of the second type of beam 1112b are arranged parallel to each other and the second bars 1112g of the second type of beam 1112b are arranged parallel to each other. That is, the second stringer 1112h includes a third bar 1112i and a fourth bar 1112j.

As shown in fig. 6, the middle frame 1112 further includes longitudinal reinforcing tubes 1112k and transverse reinforcing tubes 1112l, and the number of the longitudinal reinforcing tubes 1112k is at least two. In this embodiment, the location and installation of the longitudinal reinforcing tubes 1112k are specifically illustrated by taking two as an example. Two longitudinal reinforcing tubes 1112k are spaced apart and a second type of beam 1112b is positioned between the two longitudinal reinforcing tubes 1112 k. Each longitudinal reinforcing tube 1112k is secured at one end to a first beam 1112c and at the other end to a second beam 1112d. The transverse reinforcing tubes 1112l are disposed between the stringer 1112b and the corresponding longitudinal reinforcing tubes 1112k, and one end of the transverse reinforcing tubes 1112l is connected to the stringer and the other end of the transverse reinforcing tubes 1112l is connected to the longitudinal reinforcing tubes 1112 k. Thus, the longitudinal reinforcement tubes 1112k, the transverse reinforcement tubes 1112l, the cross beams 1112a, and the longitudinal beams 1112b collectively form a net-like structure, effectively increasing the structural strength and load carrying capacity of the entire mid-frame 1112.
As shown in fig. 8, the front frame 1111 further includes a first upright 1111h, the rear frame 1113 further includes a second upright 1113a, and the first upright 1111h and the second upright 1113a are generally referred to as a-pillar and B-pillar, respectively. First upright 1111h and second upright 1113a are used for load bearing, support and protection. One end of the first upright 1111h is connected to the first beam 1112c, and the other end of the first upright 1111h extends upward. One end of second upright 1113a is connected to second beam 1112d and the other end of second upright 1113a extends upward.
As shown in fig. 8 and 9, in one embodiment, a reinforcing structure 1114 is provided between the rear frame 1113 and the middle frame 1112 to improve the structural strength of the connection between the rear frame 1113 and the middle frame 1112. The reinforcement structure 1114 includes a first reinforcement bar 1114a, a second reinforcement bar 1114b, and a reinforcement plate 1114c. One end of the first reinforcing rod 1114a is connected to the longitudinal reinforcing tube 1112k on the middle frame 1112, and the other end of the first reinforcing rod 1114a is connected to the second upright 1113 a. Rear frame 1113 further includes a support bracket 1113y, and second reinforcement rod 1114b has one end connected to support bracket 1113y and the other end connected to second stud 1113 a. One end of the reinforcement plate 1114c is connected to the first reinforcement rod 1114a, and the other end of the reinforcement plate 1114c extends toward the rear side of the atv 100, crosses the second pillar 1113a, and is connected to the second reinforcement rod 1114 b. In this way, the reinforcing plate 1114c can distribute the acting force of the first reinforcing rod 1114a and the second reinforcing rod 1114b concentrated on the second column 1113a, thereby avoiding processes such as punching holes on the second column 1113a and reducing the possibility of local deformation of the second column 1113 a. It should be understood that only the connection manner of the reinforcing rods at the second column 1113a is illustrated here, and the above structure can also be applied to other columns, cross beams or longitudinal beams.
First reinforcement rod 1114a is welded to second stud 1113 a. Second reinforcement rod 1114b is welded to second stud 1113 a. The reinforcing plate 1114c is integrally formed by punching. The reinforcing plate 1114c is welded to the first reinforcing bar 1114a and the second reinforcing bar 1114 b. Reinforcing pieces 1114d are provided at both ends of the reinforcing plate 1114c, respectively. Each reinforcing piece 1114d abuts against a corresponding reinforcing rod. As such, to increase the contact area between the reinforcing plate 1114c and the first and second reinforcing bars 1114a and 1114b, the connection strength between the reinforcing plate 1114c and the first and second reinforcing bars 1114a and 1114b is improved.

First air inlet cavity 1125 is formed in the side face of vehicle body 112, first air inlet cavity 1125 is communicated with the outside atmosphere, one end of first air inlet pipe 1411 is connected with an air inlet of engine 121, and the other end of first air inlet pipe extends into first air inlet cavity 1125 of vehicle body 112. Gas may enter the first inlet pipe 1411 via the first inlet chamber 1125. One end of the first outlet pipe 1412 is connected to an outlet of the engine 121, and the other end extends to the rear side of the vehicle body 112, so as to facilitate the discharge of exhaust gas after the fuel is combusted. The second air pipe unit 142 includes a second air inlet pipe 1421 and a second air outlet pipe 1422, a second air inlet cavity 1126 is opened on the side of the vehicle body 112, the second air inlet cavity 1126 is communicated with the outside atmosphere, one end of the second air inlet pipe 1421 is connected with the air inlet of the transmission 122, the other end of the second air inlet pipe 1421 extends into the second air inlet cavity 1126, and the cooling gas can enter the second air inlet pipe 1421 through the second air inlet cavity 1126 to cool the transmission 122. One end of the second outlet pipe 1422 is connected to the outlet of the transmission 122, and the other end is aligned with the first outlet pipe 1412, and takes away part of the heat of the first outlet pipe 1412.
As shown in fig. 2 and 4, the first air intake cavity 1125 and the second air intake cavity 1126 are uniformly arranged at the side of the vehicle body 112, and the first air intake cavity 1125 and the second air intake cavity 1126 are arranged relatively far away from the bottom of the all-terrain vehicle 100 along the vertical direction, so that the first air intake cavity 1125 and the second air intake cavity 1126 have a sufficient height. It will be appreciated that ATV 100, as a typical recreational vehicle, is often heavily involved in water. While the first and second intake chambers 1125 and 1126 are disposed high enough at the location of the vehicle body 112. When the vehicle is wading, the first intake cavity 1125 is sufficiently high to effectively ensure the supply of the gas required by the engine 121, and the second intake cavity 1126 is sufficiently high to effectively ensure the supply of the cooling gas required by the transmission 122. Namely, the wading depth and the use place of the all-terrain vehicle 100 are improved, and the vehicle damage caused by the water inflow of the engine 121 is avoided.
Illustratively, the first intake chamber 1125 is disposed at the left side of the vehicle body 112 and near the rear side of the vehicle body 112, and the second intake chamber 1126 is disposed at the right side of the vehicle body 112 and near the rear side of the vehicle body 112. Also, the first intake cavity 1125 is located at the same height in the vertical direction on the side of the vehicle body 112 as the second intake cavity 1126 is located at the side of the vehicle body 112. With such a layout, the engine 121 and the transmission 122 can intake air dispersedly, that is, the first intake pipe and the second intake pipe 1421 are prevented from simultaneously intaking water during wading. Meanwhile, the first air inlet cavity 1125 and the second air inlet cavity 1126 are arranged on the two sides of the vehicle body 112, so that the space of the vehicle body 112 can be fully utilized, and the reasonability of the layout is improved.
Between the front and rear sides of atv 100, first intake cavity 1125 is disposed at a location near the rear side of nacelle 1121 and rear wheel set 18 near the front side. I.e., the first intake chamber 1125 and the second intake chamber 1126 are each located between the nacelle body 1121 and the rear wheel set 18. The structure of the first air inlet cavity 1125 and the structure of the second air inlet cavity 1126 may be the same or different, and may be specifically set according to actual situations. In this embodiment, the structure of the first intake cavity 1125 and the structure of the second intake cavity 1126 are configured identically to facilitate a savings in overall tooling and manufacturing. As such, the following section is directed to the first intake chamber 1125, which generally describes the manner in which the power assembly 12 is intake. Meanwhile, the following description relates to structures that can be disposed on the first intake cavity 1125, and can also be disposed on the second intake cavity 1126.
As shown in fig. 12 to 14, the frame assembly 111 further includes an air intake seat 143, a mounting cavity 1121g corresponding to the air intake seat 143 is opened on a side surface of the vehicle body 112 near the rear side, and the air intake seat 143 is partially or completely embedded in the mounting cavity 1121g. In one embodiment, the number of the air inlet seats 143 is two, wherein one air inlet seat 143 is provided with a first air inlet cavity 1125, and the other air inlet seat 143 is provided with a second air inlet cavity 1126. The left and right sides of the body 112 include mounting cavities 1121g, respectively. One of the air inlet seats 143 is at least partially embedded in the left mounting cavity 1121g, and the other air inlet seat 143 is at least partially embedded in the right mounting cavity 1121g. The rear wheel set 18 includes a left rear wheel 181 and a right rear wheel 182. Based on the locations of the first and second intake chambers 1125, 1126, the air inlet 143 is shown positioned between the body 1121 and the rear wheel set 18. One of the air intake seats 143 is located between the left rear wheel 181 and the cabin 1121, and the other air intake seat 143 is located between the right rear wheel 182 and the cabin.
The air inlet seat 143 is further provided with a third mounting hole 1431 communicated with the first air inlet cavity 1125, an axis of the third mounting hole 1431 is substantially parallel to a vertical axis, and one end of the first air inlet pipe 1411, which is far away from the engine 121, extends into the first air inlet cavity 1125 from the third mounting hole 1431 and is mounted on the air inlet seat 143. The side face of the first air inlet cavity 1125 corresponding to the vehicle body 112 is provided with a fourth opening 1432, the fourth opening 1432 is communicated with the outside atmosphere, that is, the outside atmosphere enters the first air inlet cavity 1125 through the fourth opening 1431, so as to realize normal air inlet of the first air inlet pipe 1411.
As shown in fig. 11, a baffle 1433 is covered at the fourth opening 1432, and a filtering hole 1434 is opened on the baffle 1433, the external atmosphere enters the first air inlet cavity 1125 after being filtered by the filtering hole 1434, that is, the impurities in the external atmosphere are removed through the filtering hole 1434, so as to ensure the cleanness of the air in the first air inlet cavity 1125. At least one layer of filter screen (not shown) is arranged inside the baffle 1433 or inside the filtering hole 1434, and the air entering the filtering hole is further filtered through the filter screen, so that the air entering the first air inlet cavity 1125 is cleaner, and the service life of the engine 121 is prolonged. It should be noted that the baffle 1433 may be connected to the air inlet 143 or the vehicle body 112 by a detachable structure such as a bolt, a screw, or a snap, so as to facilitate the detachment of the baffle, the cleaning and the maintenance of the interior of the first air inlet cavity 1125.
As shown in fig. 12 and 14, a third protrusion 1125a is disposed at the bottom of the first air inlet cavity 1125, the third protrusion 1125a protrudes out of the bottom of the first air inlet cavity 1125, a third mounting hole 1431 is opened on the third protrusion 1125a, the orientation of the third mounting hole 1431 is not consistent with the orientation of the fourth opening 1432, and the first air inlet pipe 1411 extends into the first air inlet cavity 1125 or is communicated with the first air inlet cavity 1125 through the third mounting hole 1431 on the third protrusion 1125 a. In this way, the position of the third mounting hole 1431 may be higher than the bottom of the mounting cavity 1121g, and may be different from the orientation of the fourth opening 1432, that is, the air intake position of the first air intake pipe 1411 is increased and the air intake port of the first air intake pipe 1411 is staggered from the fourth opening 1432. When water or other contaminants enter first intake chamber 1125 through fourth opening 1432 during operation or washing of atv 100, third lobe 1125a has a blocking and channeling effect thereon to block water or other contaminants from entering first intake duct 1411 and to channel water to an entry location remote from first intake duct 1411. Therefore, the water and other impurities at the inlet of the first air inlet pipe 1411 are blocked and guided in parallel, the double blocking of the water and other impurities at the inlet of the first air inlet pipe 1411 is realized, the waterproof and dustproof effects of the first air inlet pipe 1411 are effectively enhanced, the probability that the engine 121 is damaged due to the entering of environmental fluid or impurities and the like is reduced, namely, the failure rate of the engine 121 is reduced, and the use safety of the all-terrain vehicle 100 is improved.
Along the vertical direction, the third protrusion 1125a extends upward and the axis of the third mounting hole 1431 coincides with the vertical direction, that is, the third mounting hole 1431 faces vertically, and the orientation of the fourth opening 1432 is perpendicular to the axis of the third mounting hole 1431. In this manner, when water or other impurities enter first intake chamber 1125 from fourth opening 1432, first contact would be third lobe 1125a facing the side of fourth opening 1432, and flow into the bottom of first intake chamber 1125 under the guidance or blocking of the side of third lobe 1125a, and then flow out of first intake chamber 1125 through the fitting gap between intake seat 143 and vehicle body 112.
As shown in fig. 12 and 14, an end surface of the third projection 1125a away from the bottom of the first intake chamber 1125 is formed as an inclined surface. For convenience of explanation, the inclined surface is referred to as a third inclined surface 1125b, the third mounting hole 1431 is located on the third inclined surface 1125b, and the third inclined surface 1125b is inclined from a side of the third projection 1125a near the fourth opening 1432 to a side of the third projection 1125a far from the fourth opening 1432. And a side of the third inclined surface 1125b near the fourth opening 1432 is relatively higher than a side of the third inclined surface 1125b far from the fourth opening 1432 in a vertical direction. In this way, in the space of the first intake chamber 1125, the third projection 1125a may be positioned highest toward the side of the fourth opening 1432, and when water or other foreign substances enter from the fourth opening 1432, the water or other foreign substances may be sufficiently blocked.
Referring to fig. 12, in order to guide the outflow of water in the first air inlet cavity 1125, the bottom surface of the first air inlet cavity 1125 is also provided with a slant surface. For convenience of illustration, the inclined surface is referred to as a fourth inclined surface 1125c, and the fourth inclined surface 1125c is inclined toward the ground (i.e., the lower side) in a direction from the rear side to the front side of the all-terrain vehicle 100. When water and the like enter the first air inlet cavity 1125, under the blocking and guiding actions of the third protrusion 1125a, the water flows to the bottom of the first air inlet cavity 1125, and then is guided by the fourth inclined surface 1125c, so that the water in the first air inlet cavity 1125 can be discharged quickly and timely, and the possibility of water inlet in the first air inlet pipe 1411 caused by water storage in the first air inlet cavity 1125 is reduced.
As shown in fig. 15, the first air duct unit 141 further includes a heightened air intake duct 144, and the heightened air intake duct 144 is used for heightening the air intake position of the first air intake duct 1411 in the vertical direction, so that the atv 100 obtains a higher air intake position. Therefore, even in a deep wading place, the engine 121 assembly can be ensured not to enter water, and the normal operation of the engine 121 assembly can be maintained. It should be noted that the heightened air intake pipe 144 is an auxiliary part (aftermarket part), and the atv 100 may not be heightened during normal or normal use, that is, the heightened air intake pipe 144 is not installed. When the all-terrain vehicle 100 needs to travel in a deep-wading place (such as beach, river cross-country), the heightening air inlet pipe 144 can be directly installed in butt joint with the first air inlet pipe 1411, so that the air inlet of the first air inlet pipe 1411 is heightened. Not only convenient to use, and the installation is simpler.
As described in connection with fig. 12, one end of the raised inlet pipe 144 can extend into the first inlet chamber 1125 and be connected to the first inlet pipe 1411, and the other end of the raised inlet pipe 144 extends in a substantially upward direction away from the inlet seat. A fifth opening 1125d is opened in the first air inlet cavity 1125, the fifth opening 1125d is disposed adjacent to the fourth opening 1432, and the direction of the fifth opening 1125d is the same as the direction of the third mounting hole 1431. Meanwhile, a fifth cover plate 1125e covers the fifth opening 1125d, and the fifth cover plate 1125e covers the third mounting hole 1431 and the air inlet of the first air inlet pipe 1411 to prevent water or other foreign substances (stones, debris) and the like from entering the inside of the engine 121 from the air inlet. That is, during normal use, the fifth opening 1125d is normally closed to prevent the air inlet of the first air inlet pipe 1411 from being exposed to the outside.
Further, a wall breaking area 1124f which can be communicated with the air inlet of the first air inlet pipe 1411 and is distributed around the air inlet is arranged on the fifth cover plate 1125 e. The broken wall region 1124f is less able to withstand force than other regions of the fifth cover 1125 e. When air inlet heightening is needed, a through hole can be formed by directly breaking the wall breaking area 1124f by using a simple tool such as a hammer, and then one end of the heightening air inlet pipe 144 extends into the first air inlet cavity 1125 from the through hole and is connected with the first air inlet pipe 1411 in a sealing mode. Therefore, the complicated air inlet heightening process can be omitted, and the structure is simple. Meanwhile, the third installation hole 1431 is combined and disposed in its orientation. After broken wall district 1124f is destroyed, first intake pipe 1411 directly stretches into in first intake chamber 1125 and can be real to be connected with first intake pipe 1411, and this kind of installation in the straight line direction easily aims at and connects, does not need professional maintainer to repack, and driver or ordinary person can accomplish and increase the demand, and the operation degree of difficulty is low.
The fifth cover 1125e is made of plastic, and the wall breaking area 1124f has a strength less than or equal to that of the other areas of the fifth cover 1125 e. Thus, the wall-broken area 1124f can be easily broken compared to other areas, so that the installation step of the raised air inlet pipe 144 is simple. In one embodiment, the wall-breaking area 1124f has a wall thickness smaller than that of other areas of the fifth cover 1125e, so that the pressure-bearing capacity of the wall-breaking area 1124f is smaller than that of other areas. In another embodiment, the inner wall of the fifth cover 1125e is recessed to form a wall-breaking region 1124f on the fifth cover 1125 e. I.e. the process is repeated. Form broken wall district 1124f through the mode that sets up the groove, not only construct simply and processing is convenient, and manufacturing cost is also lower. Of course, the wall-breaking region 1124f may be formed on the fifth cover 1125e by other methods.
As shown in fig. 16 and 17, the connection between the inlet pipe 144 and the first inlet pipe 1411 is facilitated. An adapter tube 145 is arranged between the heightening air inlet tube 144 and the first air inlet tube 1411. One end of the adapter tube 145 extends into the third mounting hole 1431 and is connected to the first inlet duct 1411, and the other end of the adapter tube 145 is located in the first inlet chamber 1125 and is connected to the heightening inlet duct 144. In an embodiment, the adapting tube 145 is a rubber tube, a sealing groove 1455 is formed on a peripheral wall of the rubber tube, one end of the rubber tube is inserted into the third mounting hole 1431 and is sleeved and hermetically connected with the first air inlet pipe 1411, and an edge of the third mounting hole 1431 is clamped in the sealing groove 1455, so that the adapting tube 145 is hermetically connected with the air inlet base 143. The other end of the colloid tube is hermetically sleeved and connected with the heightening air inlet tube 144. It can be understood that, based on the material characteristics of the rubber tube, the rubber tube itself has a sealing property, which not only realizes the switching, but also improves the sealing effect between the switching tube 145 and the first inlet pipe 1411 and the heightened inlet pipe 144, respectively. Meanwhile, the rubber tube has a certain deformation amount, and on a road surface which faces a bumpy driving environment, the rubber tube is used as a joint of the first air inlet pipe 1411 and the heightened air inlet pipe 144, and has a certain buffering and vibration absorbing effect. Here, the rubber tube may be a rubber tube or a silicone tube, etc.
The adapter tube 145 includes a first connection segment 1451, a second connection segment 1452, and a third connection segment 1453, with the second connection segment 1452 being positioned between the first connection segment 1451 and the third connection segment 1453. The first connecting section 1451 is located within the first intake chamber 1125 and the third connecting section 1453 is located outside of the first intake chamber 1125 and is positioned adjacent to the first intake conduit 1411. The second coupling segment 1452 is inserted into the third mounting hole 1431 to serve as a bridge between the first coupling segment 1451 and the second coupling segment 1452. Moreover, a sealing groove 1455 is formed on the outer wall of the second connecting section 1452; the edge of third mounting hole 1431 is captured within seal groove 1455. Meanwhile, the ends of the first connecting section 1451 and the third connecting section 1453 away from the second connecting section 1452 and the second connecting section 1452 are flared, and the flares have guiding functions, so as to facilitate connection between the first inlet pipe 1411 and the heightened inlet pipe 144 and the adapter pipe 145, respectively. Here, the second connecting segment 1452 has a bellows shape. The sealing groove 1455 is formed between adjacent two peaks on the outer circumferential surface of the second coupling segment 1452.
Furthermore, the peripheries of the adapter tube 145 and the heightening air inlet tube 144 and the peripheries of the adapter tube 145 and the heightening air inlet tube 144 are respectively sleeved with a clamp 1454, and the clamp 1454 is tightly held, so that stable connection is realized and the sealing performance is improved. It should be noted that the above example illustrates a connection manner between the first intake pipe 1411 and the heightened intake pipe 144. In other embodiments, the first inlet pipe 1411 and the heightened inlet pipe 144 may be connected by snapping, screwing, or the like. The first and third connecting sections 1451 and 1453 each have a corresponding positioning groove on their outer circumferential surfaces, and the clip 1454 is fitted into the corresponding positioning groove and clamps the first connecting section 1451 and the heightened air inlet pipe 144 and the first air inlet pipe 1411 and the third connecting section 1453.
As shown in fig. 18 and 19, the raised inlet pipe 144 includes a first section 1441 and a second section 1442, one end of the first section 1441 extends into the first inlet cavity 1125 from the through hole of the fifth cover 1125e and is connected to the adapting pipe 145, and the other end of the first section 1441 extends in a direction away from the inlet seat 143 and substantially upward. One end of the second section 1442 is connected to one end of the first section 1441 away from the first intake cavity 1125, the other end of the second section 1442 serves as an inlet, and the axis of the second section 1442 is arranged at an included angle to the axis of the first section 1441. It is to be explained that water and impurities always have a tendency to move vertically downwards due to the effect of gravity. And the axis of the second section 1442 forms an included angle with the axis of the first end, that is, the axis of the air inlet forms an included angle with the vertical direction, so as to prevent water or other impurities from directly entering the heightening air inlet pipe 144 from the inlet under the action of gravity. The angle between the axis of second section 1442 and the axis of first section 1441 is greater than or equal to 40 ° and less than or equal to 140 °, and second section 1442 extends forward of atv 100 away from the end of first section 1441. In this way, the second section 1442 can be entirely inclined toward the frame 111 or the ground, so as to reduce the possibility of water or other impurities entering, and improve the safety of the use of the engine 121 assembly. In one embodiment, the angle between the axis of the second section 1442 and the axis of the first section 1441 is greater than or equal to 60 ° and less than or equal to 140 °. It will be appreciated that within the above-described angular range, the intake height of the raised inlet pipe 144 may be optimized and water, dust, etc. may also enter from the second section 1442. Preferably, the angle between the axis of the second section 1442 and the axis of the first section 1441 is greater than or equal to 80 ° and less than or equal to 110 °.
In one embodiment, the second section 1442 is disposed obliquely, and the axis of the second section 1442 is inclined downward relative to the axis of the first section 1441. One end of the second section 1442 far away from the first section 1441 is closed, and an air inlet hole 1446 is formed in one side surface of the second section 1442 facing the ground. The air inlet holes 1446 are provided with a filter 1447 for filtering the medium entering the second section 144 from the air inlet holes 1446 to ensure the cleanliness of the air entering the raised inlet duct 144. The axes of the inlet holes 1446 can be substantially parallel to the axis of the first section 1441 or can be inclined relative thereto. In this way, the air inlet holes 1446 are always arranged toward the first air inlet pipe 1411, and the gravity direction of the water or other impurities is the same as the gravity direction of the water or other impurities, so that the water or other impurities cannot enter the heightening air inlet pipe 144 from the air inlet holes 1446. Meanwhile, in combination with the way that the axis of the second section 1442 forms an acute angle with the axis of the first section 1441, even if a small portion of water or other impurities enters the second section 1442 through the air inlet hole 1446 under the guidance of the inclination of the second section 1442, the water or other impurities is stored at one end of the second section 1442 far away from the first section 1441 under the guidance of the second section 1442, and when the water or impurities are accumulated to a certain extent, the water or impurities can be discharged or removed through the air inlet hole 1446.
As shown in fig. 13 and 14, the raised inlet pipe 144 further includes a third section 1443, and the third section 1443 is located between the first section 1441 and the second section 1442. The third section 1443 is a curved section, that is, the third section is arranged in an arc shape, and the curved direction of the third section 1443 is substantially the same as the curved direction of the second pillar 1113a, so as to improve the coordination and integrity between the heightened air intake pipe 144 and the vehicle body 112 after the all-terrain vehicle 100 heightens the air intake. A first positioning step 1444 is formed between the third section 1443 and the first section 1441, and after the first section 1441 is inserted into the first air inlet cavity 1125, the first positioning step 1444 abuts against the fifth cover plate 1125e, so that the heightened air inlet pipe 144 is positioned, and meanwhile, the first section 1441 is prevented from being excessively inserted into the first air inlet cavity 1125 or the adapter pipe 145.
The heightened air intake pipe 144 is provided with a third connecting portion 1445. When the heightened intake duct 144 is connected to the first intake duct 1411, the third connecting portion 1445 is connected to the vehicle body 112. Thus, the dual positioning of the heightened air inlet pipe 144 is realized, so that the connection failure of the heightened air inlet pipe 144 between the vibration or external force of the ATV 100 and the first air inlet pipe 1411 is avoided. Here, the third connection portion 1445 and the vehicle body 112 may be connected by a quick release structure 1122e such as a bolt, a buckle, or a hoop. In one embodiment, a third connecting portion 1445 is provided on the third section 1443.
As shown in fig. 19, the raised inlet pipe 144 further includes a second fixing plate 1448, one end of the second fixing plate 1448 is fixed to the second section 1442, and the other end of the second fixing plate 1448 is used for connecting the upper body 112. Therefore, the air inlet heightening pipe 144 can be positioned in a triple manner by combining the third connecting part 1445, and the mounting stability of the heightening air inlet pipe 144 is effectively improved. In one embodiment, the second fixing plate 1448 is detachably connected to the second section 1442. So that the position between the second fixing plate 1448 and the heightened intake pipe 144 is adjustable. In this way, the connection position between the heightening intake pipe 144 and the vehicle body 112 can be adjusted, and the mounting flexibility of the heightening intake pipe 144 can be improved. Here, the second fixing plate 1448 and the second section 1442 may be detachably connected by a bolt, a buckle, or the like.
As shown in fig. 20, atv 100 further includes electrical components 19 and an electronic control unit 21. The electrical components 17 and the electronic control unit 21 are mounted on the frame assembly 11, and at least a portion of the electrical components 19 is electrically/signally connected to the electronic control unit 21 for performing basic electrical functions of the all-terrain vehicle 100. The Electronic Control Unit 21, also called an "Electronic Control Unit" or "vehicle computer", is used for monitoring various input data (such as braking, gear shifting, etc.) and various operating states of the vehicle (such as acceleration, slippage, fuel consumption, etc.), calculating information transmitted by various sensors according to a pre-designed program, processing the information, and sending various parameters to relevant actuators, such as the electrical component 19, etc., to execute various predetermined Control functions.
In one embodiment, as shown in fig. 20, the electrical component 19 includes a meter device 200 and a switch device 203. The meter device 200 includes various electric instruments such as an ammeter, a charge indicator lamp or voltmeter, an oil pressure gauge, a thermometer, a fuel gauge, a vehicle speed and mileage meter, an engine tachometer, and the like. Meter device 200 is primarily operable to display the operation of devices associated with the operation of ATV 100 during travel. The sound generating device 201 is mainly used for generating sound to play a role of prompting or warning. The switching device 203 includes a mode switching switch 2031, an air conditioning switch (not shown), a temperature adjusting switch (not shown), and the like. The mode changing switch 2031, the air conditioner switch, and the temperature adjustment switch are basically mounted on the dash panel 1122b for easy operation by the driver and the front passenger. The mode switch 2031, the air conditioner switch, the temperature adjustment switch, and the like are electrically/signal connected to the electronic control unit 21 via the wiring harness 2042, thereby controlling a series of functions of the atv 100, such as switching between the two-drive and the four-drive, turning on the air conditioner, and adjusting the temperature of the air conditioner.
As shown in fig. 21 to 24, the mode changing switch 2031 includes a two-drive position 2031a, a four-drive position 2031b, and a front-drive-lock-up position 2031c.

The first, second, and third gear grooves 2031e, 2031f, 2031j are located within the cavity 2031 za. The second gear groove 2031f is located between the first gear groove 2031e and the third gear groove 2031j. The pressing plate 2031x is rotatably connected to the housing 2031d via a switch rotation shaft 2031 t. One end of the shift lever unit 2031u is connected to the pressing plate 2031x, and the other end of the shift lever unit 2031u can swing along with the pressing plate 2031x and switch among the first shift groove 2031e, the second shift groove 2031f, and the third shift groove 2031j, thereby realizing the mutual switching among the second-drive shift 2031a, the fourth-drive shift 2031b, and the front-drive dead-lock shift 2031c.
Referring to fig. 22, the shift lever unit 2031u includes a switch lever 2031v, an elastic member 2031x, and a ball 2031y, one end of the switch lever 2031v is connected to the pressing plate 2031x and can swing within the housing 2031d under the driving of the pressing plate 2031x, one end of the switch lever 2031v away from the pressing plate 2031x is provided with a fourth mounting hole 2031w, the elastic member 2031x is mounted within the fourth mounting hole 2031w, a portion of the ball 2031y is located within the fourth mounting hole 2031w and abuts against the elastic member 2031x, and the other end can swing in a first shift groove 2031e, a second shift groove 2031f, or a third shift groove 2031j.
As shown in fig. 23 and 24, the first, second, and third shift grooves 2031e, 2031f, 2031j are arc-shaped grooves, and the first, second, and third shift grooves 2031e, 2031f, 2031j are connected in sequence. The second gear groove 2031f includes a first connection end connected to the first gear groove 2031e, and the first gear groove 2031e includes a second connection end connected to the first connection end, the first connection end and the second connection end intersecting each other and having a first intersection point P and a first included angle β 1 (ii) a The second gear groove 2031f further comprises a third connection end connected to the third gear groove 2031j, the third gear groove 2031j comprises a fourth connection end connected to the third connection end, the third connection end intersects with the fourth connection end and has a second intersection point Q and a second included angle β 2 (ii) a First included angle beta 1 At a second angle beta 2 The difference of (a) is not less than 5 ° and not more than 30 °. That is, the second shift groove 2031f has a larger gradient on the third shift groove 2031j side than the second shift groove 2031f on the first shift groove 2031e sideThe transition between the first and second gear grooves 2031e and 2031f is more gradual than the transition between the second and third gear grooves 2031f and 2031j. Thus, when the gears are switched, the damping of the switching rod 2031v switched from the second gear groove 2031f to the third gear groove 2031j is greater than the damping of the switching rod 2031v switched from the first gear groove 2031e to the second gear groove 2031f, that is, the force value for switching each gear is different, and the force value required for operation when the four-wheel drive gear is switched to the pre-drive dead-lock gear 2031c is increased, so that the phenomenon of gear over-shifting caused by directly switching the two-wheel drive gear 2031a to the pre-drive dead-lock gear 2031c when the two-wheel drive gear 2031a is switched to the four-wheel drive gear 2031b is avoided, and the driving safety is improved.

First included angle beta 1 120 degrees or more and 140 degrees or less, and a second included angle beta 2 Is 100 ° or more and 125 ° or less.
Further, the first straight section and the plane A 1 Intersect and form a third angle of inclusion beta 3 Second straight section and plane A 1 Intersect and form a fourth angle of inclusion beta 4 Fourth angle of inclination beta 4 At an angle beta to the third 3 The difference of (a) is not less than 5 ° and not more than 30 °. Third included angle beta 3 Greater than or equal to 45 degrees and less than or equal to 60 degrees, and a fourth included angle beta 4 Is 55 DEG or more and 75 DEG or less. So arranged, the second straight section 2031i can also be opposite to the plane A 1 Is greater than the first straight section 2031h relative to the plane A 1 The gradient of (c). So that a force value required for the switching lever 2031v to switch from the second gear groove 2031f to the third gear groove 2031j becomes large.
In one embodiment, the third straight section 2031k is parallel to plane A 1 Intersect and form a fifth angle beta 5 (ii) a Fourth straight section 2031z and plane A 1 Intersect and form a sixth angle beta 6 Fifth angle of inclination beta 5 Angle beta with sixth angle 6 Are substantially the same. With this arrangement, the operation force value for switching from the second-drive range 2031a to the fourth-drive range 2031b can be made substantially equal to the operation force value for switching from the fourth-drive range 2031b at the front-drive dead-lock range 2031c, thereby improving the consistency of the operation.
